Now we've all been Spidey's fans for quite a few years, and we've also read quite a bit of writing about him, be it of the "here's what you need to know about the world of the Wall-Crawler" type journalistic articles aimed at people whose only exposure to the franchise had been a movie or television adaptation to essays written by self-appointed "experts" on comicbook-related websites. What is the thing that bothers you most there when you come across it?
For Stan Lee it is, by his own admission, when people spell Spider-Man without the hyphen ("Spiderman").
For me it is when people compare the (actually quite short-lived) Gwen-Peter-Mary Jane triangle to Betty Cooper, Archie Andrews and Veronica Lodge, especially when, as happens most of the time, they then go on to portray as a simple, wholesome "girl next door" like Ms. Cooper (because both are blondes) and MJ as a glamorous society type like Ms. Lodge (because both aren't blondes), almost completely ignoring the actual state of affairs and the differences in principle between the two set-ups (such as Peter clearly being Gwen's boyfriend, not MJ's) all the way to Gwen's death.
So what is your pet nerd peeve?
Mine is when writers try to overstate subtle aspects of the character. Yes, Peter Parker had bad luck but when "The Parker Luck" becomes the focus of the story, I don't like it. The Parker Luck was more the way that Peter coped with what was happening as opposed to an actual thing. Most teenagers think they have bad luck.
Yes, Spider-Man is close to the FF and the Human Torch especially but that doesn't justify the "we're family" feels.
Don't take such things overboard. That's when the story writes the character instead of the other way around.
